' Mimmo JOI-IN WESLEY BROWN, OF ARROYO GRANDE, CALIFORNIA.

BEAN-CUTTER.

Specification of Letters Patenti Patented Sept. 17, 1907.

Application filed May 27,1907. Serial No. 375,934.

To all whom it may concern:

Be it known that I, JOHN WESLEY BROWN, a citizen of the United States, residing at Arroyo Grande, in the county of San Luis Obispo and State of California, have invented certain new and useful Improvements in Bean-Cutters; and I do declare the following to be al full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same. A

My invention has relation to new and useful improvements in bean cutters, and has for its main object to provide an improved form of knives and guards, and means for adjusting the same either vertically or laterally.

With this and other objects in view that will readily4 appear as the nature of the invention is better understood, my invention consists of certain novel features of construction and combination oi parts illustrated in the drawings and particularly pointed out in the specification and claims hereunto appended.

In the accompanying drawings-Figure l is a top plan view of my invention; Fig. 2 is a side elevation; Fig. 3 is a longitudinal sectional view on the line 3 3 of Fig. 1; and Fig. 4 is a cross sectional view on the line 4 4 of Fig. l, looking in the direction of the arrows.

The frame oi my invention comprises two side pieces 1 connected near their iront and rear ends by cross bars 2 and 3, respectively, and angular braces 4, secured at their lower ends to the outer sides of said side pieces and at their inner edges to the under sides of said cross bars. Each of said side bars l is provided in its under edge and near its front end with a longitudinal recess 5, and secured to the under edges of said side pieces l are longitudinal runners, having Asuitable upwardly extending bent portions 7, corresponding in length with and adapted to fit in the said longitudinal recesses oi said side pieces 1.

The numeral 8 represents two oblique cutting knives, which are pivotally secured at their front ends to the under sides of the upwardly extending bent portions 7 of the runners 6, by suitable means. The rear ends oi said knives are adj ustably held in position by means of adjusting hangers 9 secured at their Alower ends to the upper faces and near the centers of said cutting knives 8 and having horizontal outwardly extending threaded portions 10 adapted to work in vertical elongated slots l1 in said side pieces 1, adjacent said hangers and having disposed on their threaded portions wing nuts l2 for holding said adjusting supporters in position. Said adjusting hangers 9 may also be provided with suitable washers 13, which work on the threaded portions of the same and are adapted to be clamped against the inner faces of vertical bearing plates 14, secured to the inner sides of said side pieces l and having vertical elongated slots to correspond with the vertical elongated slots in .said side pieces. Vertical bearing plates 15 having slots to correspond with the slots in said side pieces may be also secured to the outer sides of the same and serve as bearings for said wing nuts l2. When the rear ends of said cutting knives 8 are in their highest position the under sides of the' same are preferably flush with the under sides of said runners, which ieature is permitted by reason of the longitudinal recesses 5 in said side pieces, and the upwardly extending bent portions 7 of said runners 6. In this position said knives work on a level with the ground and do not plow up the dirt and cover up the bean vines, but if desired, may be lowered to run in the ground.

The numeral 16 represents two vertical retaining knives, which are adjustably secured by means of elongated slots 17 in their upper parts and bolts and wing nuts 18 and 19, respectively, to the outer sides and near the rear ends of said side pieces 1 of said frame. The lower ends of said retaining knives, 16, extend below the undersides of said longitudinal runners 6 and penetrate into the ground to prevent lateral displacement of their extreme front ends in vertical elongated slots 2l in and near the front ends of said side pieces by bolts, adapted to work through said vertical elongated slots 21, and having nuts disposed on their threaded ends. The rear ends of said oblique rearwardly extending guards 20 are held in position by means of supporting screw eyes 22, or other equivalent means, adapted to work in vertical elongated slots 23 in and near the front ends of said side pieces, rearward of said slots 21 and having washers on their threaded ends adapted to be clamped to the outer sides of said side pieces by nuts 24.

It will be obvious that by the construction just above described, said oblique rearwardly extending guards 20 may be raised or lowered a predetermined distance, as occasion may necessitate. The rear ends oi said oblique cutting knives 8 may be adjusted at any desired distance apart, which adjustment is facilitated and permitted by reason of the outwardly extending threaded portions 10 of said adjusting hangers 9.

25 represents a combined draft tongue and guide hanger, which is secured to the under and upper faces of said cross bars 2 and 3, respectively, and is provided at its front end with a clevis 26, or 'other equivalent means, for the adjustment of draft means, and is preierably reduced at its rear end to provide a handle for guiding the machine.

Having described my invention, I claim:-

1. In a bean cutter', the combination of a frame, cornprising side pieces connected near their front and rear ends hy cross bars and having longitudinal recesses in their' under edges near their front ends, longitudinal runners having upwardly extending bent portions corresponding in length with the recesses in said side pieces, secured to the under edges of the same, oblique cutting knives pivotally connected at their front ends to said longitudinal runners at their bent portions, adjusting hangers connected at their lower ends to the ripper' faces of said oblique cutting knives and having horizontal outwardly extended threaded portions adapted to work in vertical elongated slots in the side pieces of said frame, retaining knives vertically and adjustably secured to the outer sides and near the rear ends of the side pieces of said frame, their lower ends adapted to penetrate into the ground, and oblique rearwardly extending guards adjustahly secured near their front ends near the front ends of said side pieces of said frame, substantially as described.

2. In a bean critter', the combination of a frame having side pieces connected near their' front and rear ends by cross pieces, longitudinal runners secured to the under edges of said side pieces, retaining knives adjustably secured near the rear ends of the side pieces of said frame, oblique cutting knives pivotally connected at their front ends to the under sides of said runners, means for supporting said cutting knives and for adjusting and holding their rear ends any desired distance apart, and oblique rearwardly extending guards adjustably secured near their front ends near the front ends of said side pieces of said trarne.
